In this paper, the advanced oxidation processes of photocatalytic oxidation and Photo-Fenton oxidation were used in degradation of emerging pollutants saccharin sodium. The concentration of saccharin sodium was determined by HPLC. The results showed both photocatalytic oxidation and Photo-Fenton oxidation had an effective degradation of saccharin sodium. The degradation process was followed the first-order reaction. The best conditions of photocatalytic oxidation system: 500W mercury lamp, 0.04 g TiO2, pH=7 and the best ratio of photo-Fenton was SAC:H2O2:Fe2+=5:60:1. The total organic carbon (TOC) of sample has significantly reduced to about 93% by the two systems.

Potassium permanganate process is an advanced oxidation technique that can provide a resolution removing organic matter in contaminated water. In this paper, the combination of composite potassium permanganate and a certain coagulant used in this process, which it was particularly suited to rapidly oxidize and degrade pollutants. It was an effective enhanced coagulation, advanced oxidation technique that could be conducted in a normal micro-polluted water environment. A series of experiment results demonstrated that the best adding quantity of composite potassium permanganate was 1.5-3.0mg/l, the best adding quantity of PFS as the coagulant was 25mg/l. Under the above conditions, potassium permanganate oxidation obviously reduced to each pollution index and greatly improved the water quality of purification of micro-polluted water. Furthermore, the organic removal rate with composite potassium permanganate was more than the unitary potassium permanganate process and the current traditional process.

A large amount of arsenic-containing solid waste is produced in the metallurgical process of heavy nonferrous metals (copper, lead, and zinc). The landfill disposal of these arsenic-containing solid waste will cause serious environmental problems and endanger people’s health. An electrochemical advanced oxidation experiment was carried out with the cathode modified by adding carbon black and polytetrafluoroethylene (PTFE) emulsion. The removal rate of arsenic using advanced electrochemical oxidation with the modified cathode in 75 g/L NaOH at 25 °C for 90 min reached 98.4%, which was significantly higher than 80.69% of the alkaline leaching arsenic removal process. The use of electrochemical advanced oxidation technology can efficiently deal with the problem of arsenic-containing toxic solid waste, considered as a cleaner and efficient method.
